Question

how an electrical heater is connected to power supply​

Answer 1

Answer:

Here is your answer

Explanation:

p.d. = 230 V, I = 8A

(a) I = Q/t

8 = Q/t

Q = 8 × 1 = 8C

So, 8c of charge flows around the circuit each second .

(b) Energy transferred = Work done

p.d. = Work done/Charge moved

230 = Work done/8

Work done = 230 × 8 = 1840 J

Energy transferred = 1840 J
